Hah! I built something similar (but very amateur) as my master thesis project: https://procrastinative.ninja/2015/02/19/sensation-suit/

I always wanted to use TENS and EMS but my professors were a bit cautious. Anyway I've learned a lot and it was a really fun project. I still have the suit and have currently lent it to a fellow student who want's to survey if and how it increases VR immersion. Very happy to see another professional go at this! Good luck guys!
